Abstract
Nitroimino (R = N-NO2) energetic material is a unique class of high energy density materials (HEDM). Synthesis and characterization of insensitive nitroimino compounds are a major challenge. Here triazole-based nitroimino compounds and their high-nitrogen green energetic salts in excellent yields are described. These materials exhibit high positive heats of formation (7.84 to 735.29 kJ mol-1), good densities (1.66 to 1.98 g cm-3), suitable detonation properties (P = 22.02 to 31.88 GPa; D = 7472 to 8936 ms-1) and high ballistic properties (Isp 205.66 to 295.35 s; C* = 1065 to 1832 ms-1) with good thermal (Td = 136-378 °C) and mechanical stabilities (IS = 10-40 J and FS = 120-360 N).
